IB/srp: Remove stale connection retry mechanism
Attempting to connect three times may be insufficient after an initiator system tries to relogin, especially if the relogin attempt occurs before the SRP target service ID has been registered. Since the srp_daemon retries a failed login attempt anyway, remove the stale connection retry mechanism.
